But the root of the problem is that multiple different cgraph_nodes share the
same name, so even if two or more nodes like that have counters == 0 we would
get the same conflict. Unless it's always the case that the additional
cgraph_nodes with the same decl name are made as copies of the original one and
their counter values are copied as well - I'm not sure if things actually work
like that, I'm just guessing...
